William and Angela are college students discussing how ethanol $(E_1{C}_2{H}_{5}OH)$ can be produced by

the fermentation of sugars $(S,C_{7\mathrm{.}2}{H}_{12\mathrm{.}3}{O}_{8\mathrm{.}25})$ in the presence of yeast according to the following

unbalanced chemical reaction: $C_{7\mathrm{.}2}{H}_{12\mathrm{.}3}{O}_{8\mathrm{.}25}(I)C_2{H}_{5}OH(I)+C{O}_2(g).$ Flowing into the reactor at

$25\mathrm{.}0C$ and $118mo\frac{l}{?}$ day are water $(W,H_{2}O)$ with a mole fraction of $0\mathrm{.}952,$ sugars with a mole fraction

of $0\mathrm{.}041,$ and the balance yeast $(Y).$ Water is an inert component, and yeast can be consider a non$-$

consumable catalyst. The reactor effluent contains water, yeast, unreacted sugars, ethanol, and

carbon dioxide $(C{O}_2).$ At $49\mathrm{.}0C,$ the stream exiting the reactor contains $13\mathrm{.}9mo\frac{l}{?}$ day carbon dioxide.

Determine some unknown component molar flow rates.
